This invention has for its object a four barreled pistol having a single striker which is brought by rotation to register in succession with each of the barrels. The axes of 5 the four barrels pass through the four vertices of a quadrangle, the intersection points of the diagonals of said quadrangle being also the center of rotation of the striker. striker is eccentrically mounted. on the hammer, which is constituted by a small cylinder revolubly mounted on its axis on the end of an oscillating lever actuated by the trigger. When the hammer is brought into the cocked position, the small cylinder carrying the striker performs the fourth part vof a revolution on its axis. At the end otits stroke the lever is released under the action of a spring and the striker hits the cap of one of the four cartridges causing the iiring. The arrangement producing the rotation of the small cylinder and striker is constituted by a ratchet and pawl mechanism, the four teeth of which are arranged on the cylinder end opposed to the end carrying the striker, while the pawl follows the lever during its oscillation and by its oscillation on another pin causes the cylinder to advance by one tooth.

The cooking releasing and percussion mechanism is carried by a frame forming also the arm stock, to whichis secured the barrel block revolving on an eccentric pin, namely outside the quadrangle enclosing the barrel bores, so thatV introduction of the cartridges and extraction of the fired cartridge cases will be possible. e

Normally and particularly during ring, the barrel block is maintained in place by suitable groove and tongue joints forming a shoulder and by a closure device lthe opening of which brings the striker o ut of operation.

The loading 1s effected by inserting the cartridges individually (except when a simultaneous loading device, easy to be constructed but of little use for the purpose of this invention, is used), while vthe four red cartridge cases are extractedsimultaneously by means of a star-shaped extractor having a pin passing longitudinally through,r the axis of the barrel block from which it protrudes in such a way as to be pressed directly The tion 7 provided with ears 7', in which is tin Fig. S--comes into contact with the teeth orfindirectly vagainst theqaction of a barrel i spring.' y f The annexedv drawing shows by way of 'example the pistol forming the object of this invention, its stockV elements having been removed in order to make its inner members visible. Y i i Fig. 1 is a front view of the arm. l. Fig. 2 is a side view thereof. l Fig. 8 is a longitudinal section of the arm through lits middle plane when ready for firing. i' Fig. 4 is a front view of the mechanism causing the rotation ofV the cylinder Y, and striker, the stock being sectioned'at itsrear 65 part.` y

Figs. 5 and 6 show in two di'lferent posi- Vtions the closure Amechanism of the barrel block acting also 'as safeguard'during loading and extraction.` y

The arm Jframe is in the form of a stock and consists of a case closed at its vrear end by a wall 1 and at its front end by the trigger guard. The upper-wall of said case comprises a higher rear portion 3 carrying a pin 2O on which the barrel block 18 ,oscillates and a lower cradle-shaped front portion 4 receiving the barrel block and provided with grooves in which engage ribls of said block and anintermediate vertical portion 5'pr0- 80 vided with four holes 5 through which the striker passes during operation. j The lower partv of lsaid case comprises a portion A6, a guard 2 and an intermediate ported the pin onA which the lever 8 carrying the hammer voscillates.

The rear,` wall 1 is provided with ears 1 carrying the pin, of the lever 9 on which the pawl producing therota'tion ot the hammer cylinder is'mounted;l Said cylinder 10 'is revolubly mounted onthe end of ythelever ,8 and carries onone side a 'liange 11 with an ,eccentric strikerQlQ and on the other side a .ring 13 secured thereonby a screw and hav-l ing four teeth 14 with inclined faces* The lever Qcarries at'its end (Fig. 4) a spring vpawl 15, which-oscillating fromv'thel position shown in Fig. 2 to the position shown 14 caulsing the cylinder 10 to perform the fourth part of a revolution, said lever being inoperative during the return oscillation. The levers 8 and 9 are connected kinetically by means of a slot 8 and pin 16 provided in one of said levers and a slot 9 provided in the other lever and in Which passes the said pin. The lever 8 is provided at its lower end With a helical spring 17 holding it from back oscillation and forcing it forward for the percussion.

The barrel block 18 has four bores 19, the axes of Which (Fig. l) pass through the vertices of a quadrangle, the Wall being provided with funnel shaped holes 5 registering With said barrel bores and through which the striker 15 successively passe's at each full oscillation of the lever 8. The barrel block 18 is held in ContactV with the stock by means of a pin 20 secured to the Wall 3 by a plug, the barrel block revolving on said pin. During firing the pressure is transmitted to the cradle 4 of the stock through the grooves 4 and 4A, in Which engage the ribls 18 and 18. The normal position of the block 18 in the cradle 4 is ensured by a latch, as it Will be hereafter described.

The block 18 yis rotated through one half revolution, as shown in dotted lines in Fig. 2, for the purpose of effecting the loading of the barrel and thel extraction of the fired cartridge cases. This operation may be effected by means of a star-shaped extractor 21 operated by meanls of a rod 22 mounted in a longitudinal opening of the barrel block and slightly protruding from the front end of said block. By pressing said rod, the eX- tractor is brought out With the cartridge cases; a spring 23 returns the rod 22 into its rest position as soon as the pressure on the rod is released. V

The cocking and firing are effected by pressing on the trigger 24 pivoted on the cradle '4. Said trigger isY substantially constituted by a plate having a deep groove, in Which are pivotally mounted the levers 25 and 26, this latter acting as a sear.

The tWo springs 25 and 26 tend, the former to return the triggerr into its rest position forcing the lever 25 against the cradle l 4 the second to cause the lever 26 to slide against the lever 8 causing'it to oscillate until it enters the slot 8', at which time the lever 8 is relealsed and causes the striker to hit one of the four cartridges. The trigger when released returns to its rest position and is ready vfor a new shot. l d

Figs. 5 and 6 shovv the closure device of the block 18. The rib 18 of this latter is provided with a longitudinal cut in which engages a tooth 27 of a lever 27 pivotally mounted in the stock, an extension 27 of the lever 27 abutls against the lever 8. By causing the lever 27 to oscillate from the position of Fig. 5 to the position of Fig. 6, the

venting hitting, through an accidental release during handling, a cartridge not yet fired. Said lever 27 may be so formed as to act as a safety device.

The characteristic devices above described `may of course be used in connection With any iirearin other than a pistol Without departing from the scope of this invention.
